Well, because it wouldn't make any difference. This is down in my basement where there was a 120-volt 20 amp circuit not being used at all in an old washer and dryer location. This tent and the equipment that runs this tent is the only thing on that circuit. I could run 240 volts to the drivers however as far as saving anyting, it wouldn't. The Mean Well driver's don't really run any more efficient at 240 volts than they do at 120.Riddle me this, oh master of the cob lights......are your drivers voltage sensing? If so, why not run 220 and use half the amps? Just curious, that's all. I love that gauge too, where did you find that?
And as you can see from the meter on the lights once I include my little 100 watt heater and my 4" exhaust blower and the humidifier I'm still only pulling less than 5 amps from this 20 amp circuit. If I was running a much bigger operation here than it would make sense to run at 240 volts just to save me a breaker space in my breaker box. But as far as power saving there is no difference between pulling 10 amps at 120 volts or 5 amps at 240 volts. It's the same amount of kilowatt-hours either way.
I bought those little meters online. They work really well for especially my bigger arrays where I have rows of 3000k cobs and rows of 5000k cobs. I'll post some pictures of my bigger controller with all of the meters that are under my 25 table array right now. It's actually perfect timing to do so because I was just replacing a potentiometer on the unit I'll post some pictures of momentarily.
If you would like a link to where I buy those meters just send me a PM and I'll get it to you. They're only like $10 a piece
